고준호 한국기술교육대학교 2017 국내박사

본 논문에서는 GEANT4(GEometry ANd Tracking) 시뮬레이션을 이용하여 의료용 전자 선형가속기 기반 BNCT(Boron Neutron Capture Therapy)를 위한 하이브리드 광중성자 컨버터를 최적화하였다. 광자 컨버터를 최적화하기 위해 다양한 재질(Au, Pb, Re, Ta, W), 형상(원통, 구, 반구(곡면), 반구(평면)), 반지름(0∼2 cm) 및 두께(0∼10 mm)에 따른 다양한 광자 컨버터가 설계되었다. 설계된 광자 컨버터는 6, 10, 15 MeV 전자빔에서 시뮬레이션되었다. 시뮬레이션 결과로부터 텅스텐 재질, 원통 형상, 반지름 1.5 cm, 두께 0.8∼2 mm 범위로 설계된 광자 컨버터가 최적화되었음을 확인하였다. 콜리메이터를 최적화하기 위해 다양한 재질(Fe, W, Pb), 길이(100, 140, 180 mm), 구멍 형상(슬릿, 원뿔) 및 구멍 면적(5×70, 9×70, 12.5×70, 27×70, 5×50 mm)에 따른 다양한 콜리메이터가 설계되었다. 설계된 콜리메이터는 6, 10, 15 MeV 전자빔에서 시뮬레이션되었다. 시뮬레이션 결과로부터 텅스텐 재질, 140 mm 길이, 슬릿형 구멍, 구멍 면적 5×70 mm로 설계된 콜리메이터가 최적화되었음을 확인하였다. 광중성자 컨버터를 최적화하기 위해 다양한 재질(Th, W, U, Ta, BeD2, BeO, Be, D2O, Al, Zn, Ni, Ce) 및 두께(0∼100 cm)에 따른 다양한 광중성자 컨버터가 설계되었다. 설계된 광중성자 컨버터는 10, 25, 50 MeV 전자빔에서 시뮬레이션되었다. 시뮬레이션 결과로부터 텅스텐(반지름 11.5cm, 두께 3 cm), 산화베릴륨(반지름 43.5 cm, 두께 20 cm), 우라늄(반지름 8 cm, 두께 3 cm)으로 설계된 광중성자 컨버터가 최적화되었음을 확 인하였다. 최적화된 광자 컨버터 및 광중성자 컨버터를 기반으로 새로운 구조의 하이브리드 광중성자 컨버터를 설계했다. 설계된 하이브리드 광중성자 컨버터는 한 개의 광자 컨버터와 두 개의 광중성자 컨버터로 구성된다. 광자 컨버터 바로 옆에 위치한 첫 번째 광중성자 컨버터는 재질로 텅스텐 또는 우라늄을 사용하고, 두 번째 광중성자 컨버터는 재질로 산화베릴륨을 사용한다. 설계된 하이브리드 광중성자 컨버터는 10, 25, 50 MeV 전자 빔에서 시뮬레이션되었다. 시뮬레이션 결과, 설계된 하이브리드 광중성자 컨버터는 BNCT를 위한 열외중성자 생성에 최적화되었음을 확인하였다. 본 논문에서 얻어진 GEANT4 시뮬레이션 결과의 검증은 MCNPX(Monte Carlo N-Particle Extended) 시뮬레이션 결과와의 비교를 통해 수행되었다. GEANT4의 표준 전자기 물리 패키지의 경우 모든 시뮬레이션의 오차는 0.05% 미만인데 비하여 MCNPX의 경우의 모든 시뮬레이션의 오차는 0.3% 미만이었다. 두 시뮬레이션에서의 광자 및 중성자 스펙트럼 결과는 큰 차이가 나타나지 않았으며, 이로부터 시뮬레이션 결과들의 타 당성이 확인되었다. In this thesis, a hybrid photoneutron converter was optimized using GEANT4(GEometry ANd Tracking) simulation for BNCT(Boron Neutron Capture Therapy) based on a medical electron linear accelerator. For photon converter optimization, various photon converters were designed according to various materials(Au, Pb, Re, Ta and W), shapes(cylinder, sphere, hemisphere(convex) and hemisphere(plane)), radius(0∼2 cm) and thicknesses(0∼10 mm). The designed photon converters were simulated based on 6, 10 and 15 MeV electron beam. From the simulation results, it was showed that the designed photon converter with tungsten material, cylindrical shape, radius 1.5 cm and thickness 0.8∼2 mm could be optimized. For collimator optimization, various collimators were designed according to various materials(Fe, W and Pb), lengths(100, 140 and 180mm), aperture shapes(slit and cone) and aperture areas(5×70, 9×70, 12.5×70, 27×70 and 5×50 mm). The designed collimators were simulated based on 6, 10 and 15 MeV electron beam. The simulation results showed that the collimator could be optimized with tungsten material,140 mm length, slit shape aperture and 5x70 mm aperture area. For photoneutron converter optimization, various photoneutron converters were designed according to materials(Th, W, U, Ta, BeD2, BeO, Be, D2O, Al, Zn, Ni, Ce) and thicknesses(0∼100 cm). The designed photoneutron converters were simulated based on 10, 25 and 50 MeV electron beam. From the simulation results, the photoneutron converter could be optimized using tungsten material (radius 11.5 cm and thickness 3 cm), beryllium oxide material(radius 43.5 cm and thickness 3 cm) and uranium material(radius 8 cm and thickness 3cm). Finally, a hybrid photoneutron converter based on the optimized photon converter and photoneutron converter was designed. The designed hybrid photoneutron converter was composed of one photon converter and two photoneutron converters. The first photoneutron converter next to the photon converter used the tungsten or uranium as material, and the second photoneutron one used the beryllium oxide as material. The designed hybrid photoneutron converters were simulated based on 10, 25 and 50 MeV. From the simulation results, it was confirmed that hybrid photoneutron converter was optimized to epithermal neutron production for BNCT. The verification of GEANT4 simulation results in this thesis was performed through a comparison with MCNPX(Monte Carlo N-Particle Extended) simulation results. For standard electromagnetic physics packages of GEANT4, all simulation errors were less than 0.05%, whereas the ones of MCNPX were less than 0.3%. The photon and neutron spectrum results in both GEANT4 and MCNPX simulations did not indicate a significant difference. Therefore, the feasibility of the simulation results was confirmed.

(An) extended PIM-SM protocol for efficient data transmission in IPTV services

고준호 한양대학교 대학원 2010 국내석사

IPTV (Internet Protocol Television) is defined as multimedia services delivered over IP based networks. This can be performed using the PIM-SM (Protocol Independent Multicast - Sparse Mode) multicast routing architecture which enable IP multicast routing on existing IP networks. The RP (Rendezvous Point) is required for network running PIM-SM, and the RP location changes the efficiency of multicast data packets. In general, the PIM-SM is consisted of a shared tree, called RPT (RP Tree) for keep-alive packets and a source-based tree, called SPT (Shortest Path Tree) for sending out large data. Therefore, the RP utilization is very high when the access network uses PIM-SM. And PIM-SM protocol can not be applied in different architectures with access networks such as PON (Passive Optical Network), HFC (Hybrid Fiber Coaxial), etc. In this thesis, a new PIM-SM protocol, to reduce the number of processes for RPT configuration and to deliver multicast data packets immediately through the SPT in IPTV services, is presented. The traditional PIM-SM and proposed extended PIM-SM protocol are compared using OPNET modeler. The simulation results show that the RP utilization, in extended PIM-SM, reduces about 58% compared with traditional PIM-SM. And this proposed PIM-SM can be applied in different architectures with access networks because the RP router is assumed to be an Edge-router.

사도행전과 로마서에 나타난 로마 모티프 연구

고준호 호서대학교 연합신학전문대학원 2010 국내석사

The Purpose of this thesis is to investigate the 'Rome'-motif reflected in the Acts and the Romans, by analyzing the theological implications carried by Luke and Paul. Performing this task, we are fully aware of danger of forcedly harmonizing theological intentions, differently expressed by the two New Testament authors: It was Spain that Paul regarded as 'the end of earth', to which his Gospel is to be preached, while Luke explicitly clarifies it as Rome (ex. Acts 1:8). Interestingly enough, Luke is different from Paul in describing 'Rome'. The third Evangelist does not report Paul's missionary works in Rome in detail, except for the short remark about his situation as prisoner (Acts 28:30-31). Some scholars note that this description does not go along with Paul's special interest in the Roman Christianity, as it is reflected in Rome 1:8-15; 15:14-29. If Luke knew actually the last activities and martyrdom of the apostle, why is Luke entirely silent about this important story? The exegetical observations we made lead us to assume that it was totally out of concern for Luke to report how Paul accomplishes his missionary task in Rome, but the author of Acts wants to depict that the Gospel, initiated in Jerusalem and expanded through Judea and Samaria, was finally preached in Rome, namely the center of the world in those days. For Paul himself, Rome was important for a different reason. He tried to have financial support from the Christians in Rome, by showing them how his Gospel has relevance both Jews and Gentiles. If Rome - a politically and religiously important city - would not acknowledge the Gospel of Paul, this would mean that his mission for Gentiles resulted in complete failure. That is why the apostle desperately tries to demonstrate his Gospel to a community that he did not found nor even visited. To sum up, Rome was important for both Paul and Luke, but from different perspectives. That is to say, Rome was a theological destination for the evangelist, while it was practical starting place for the apostle's another mission. These different theological implications converge in common concern in the primitive Christianity: mission. It was a pivotal strategy for survival. The mission was not an option, but the sine qua non for the first Christians, in order to survive. With this to be true, we may conclude that the different descriptions of Rome, found in Acts and Romans, reflect this dynamic in expansion of the early Christianity.

조기 강도 발현을 위한 시멘트 모르타르의 기초물성 및 내구성 평가

고준호 대진대학교 대학원 2007 국내석사

급격한 산업화의 추진과 더불어 건설되기 시작한 많은 사회간접자본시설물들은 성능이 저하됨에 따라 노후화가 많이 진행되어 이에 따른 유지관리가 요구되고 있다. 이러한 사회간접자본시설물들은 사용성에 문제가 발생하면 많은 경제적인 손실을 가져오기 때문에 신속한 보수보강공사가 필수적으로 요구된다. 본 연구에서는 초속경시멘트(Rapid Hardening Cement)의 제조방법이 상이한 클링커 형태의 초속경시멘트(A형)와 혼화재 형태의 초속경시멘트(B형)를 선택하여 기초물성, 강도특성 및 내구성능을 평가하기 위하여 초속경시멘트의 종류 및 혼입율이 상이한 모르타르를 제작하여 보통포틀랜드시멘트와 비교평가 하였다. 이상의 실험결과 초속경시멘트를 사용한 모르타르의 경우 수화초기에 에트링가이트가 다량 생성되는 모습을 볼 수 있었으며, 이러한 에트링가이트에 의해 급결성이 발현되는 것으로 판단된다. 혼입율을 달리한 초속경시멘트 모르타르의 압축강도와 부착강도를 측정한 결과 A형 초속경시멘트를 사용한 모르타르의 경우 혼입율이 50∼70%를 혼입한 시멘트 모르타르의 압축 및 부착강도가 우수한 강도발현특성을 나타낸 반면, B형 초속경시멘트 모르타르의 경우에는 보통포틀랜드시멘트 모르타르에 비하여 부착성능이 상당히 저조하게 측정되어 보수보강시 부착강도 발현특성을 고려해야할 것으로 사료된다. 한편 전위차 염소이온 확산실험결과 두 종류의 초속경시멘트 모르타르 모두 초속경시멘트의 팽창성에 의해 보통포틀랜드시멘트 모르타르보다 확산계수 및 침투깊이가 높게 나타나 유해이온에 대한 적절한 대책이 마련되어야 할 것으로 사료된다. 이상의 초속경시멘트를 사용하여 제조한 모르타르의 초기수화특성, 유동성 및 응결특성과 압축, 부착강도실험 결과 보통포틀랜드시멘트 모르타르와 비교하여 우수한 성능을 나타내었다. 하지만 제조사에 따라 다른 특성을 지니고 있으므로 충분한 실험 및 검토를 통하여 사용함에 있어 신중을 기해야 할 것이며, 아울러 장기내구성에 대한 검토도 이루어져야 할 것으로 판단된다. The function of the infrastructure constructed in the rapid industrialization period has now deteriorated and requires maintenance and repair. As there are huge economic damages if the infrastructure has problem in usage, it is necessary to repair and strengthen the infrastructure promptly. This study aims to evaluate the basic physical properties, strength and durability for the Rapid Hardening Cement(hereinafter RHC) in the shape of a clinker (A-type) and the RHC in the shape of admixture(B-type). The mortar of the RHC with different kinds and replacement ratios were made to be compared to the Ordinary Portland Cement(hereinafter OPC). The results of the experiments showed that a considerable amount of Ettringite was generated in the initial stage of the hydration in the case of the mortar which used the RHC, and it is thought that the quick setting is done by the Ettringite. The compressive and adhesive strength of the mortar with the RHC in different replacement ratio was measured. In the case of the mortar which used the A-type RHC, the compressive and adhesive strengths of the mortar were superior with the 50∼70% of replacement ratio. On the other hand, the adhesive strength of the mortar which used the B-type RHC was considerably lower than that of the OPC and thus needs to consider the expression of the adhesive at the time of the repair and strengthen. In the meantime, the results of the diffusion test for the potential difference chloride ion showed that both of the two kinds of mortar made with RHC had a higher diffusion coefficient and penetration depth than the OPC due to the expansibility of the RHC and thus it is thought necessary to prepare appropriate measures for the harmful ion. According to the experiment for the characteristics of the initial hydration, fluidity, setting time, compressive and adhesive strength of the mortar made with the RHC, the mortar was superior in performance to the OPC. However, as there are different characteristics according to different manufactures, it is necessary to pay careful attention to its usage through sufficient experiments and studies and make research on the long-term durability.

어린이 생활안전관리에 관한 연구 : 통학버스 안전사고를 중심으로

고준호 경희대학교 공공대학원 2014 국내석사

우리나라의 최근 몇 년 사이에 발생한 어린이 사망원인을 분석한 자료를 보면 가장 많이 차지하는 사망원인 1순위가 안전사고였으며, 그 중 어린이교통사고가 차지하는 비중이 절반이었다. 이처럼 어린이교통사고가 많이 발생하는 여러 원인을 분석한 도로교통공단 자료를 분석해 보면 중앙선 침범, 신호위반, 안전거리 미확보, 안전운전의무불이행. 교차로 통행방법 위반, 보행자 보호의무위반 순으로 조사되었다. 첫째, 운전자가 교통관련법규를 지키지 않아서 발생하는 사고 중 안전 의무불이행, 신호위반, 중앙선 침범 등의 교통관련법규와 관련된 문제점. 둘째, 어린이통학버스 교통사고 중에는 대부분 어린이 보호구역에서 발생한 사고에서는 어린이보호구역의 운영방안의 문제점. 셋째, 어린이 통학버스 사고의 주된 원인 중에는 통학버스 운전자의 과실로 인해 발생하는 경우는 운전자의 관리에 대한 문제점. 넷째, 어린이는 성인에 비해 정신적, 신체적으로 미약하고 교통교육이 이 제대로 이루어지지 않아 교통사고에 대한 대응능력이 떨어져 많은 희생자가 발생하는 경우 어린이교통사고 예방교육과 관련된 문제점. 위에서 살펴본 것처럼 어린이교통사고 발생 원인으로 지적되는 4가지 문제, 어린이보호구역운영방안, 교통관련법규와 제도, 운전자의 관리, 어린이교통사고예방교육에 대해서 연구해 보기로 하였다. 이에 본 연구의 목적은 이러한 어린이통학버스 안전사고를 4가지로 구분하고 그에 따른 선진국 사례의 검토를 통해 안전사고의 개선방안을 고민했으며, 그에 따른 해결 방안으로 교통선진국인 미국, 영국, 독일, 일본의 사례를 통해서 개선방안을 제시 하였다. 그 결과 어린이 보호구역의 운영에 있어서는 강력한 법률 강화와 처벌이 동시에 개선되어야 하며, 교통선진국의 경우처럼 교통정온화(Traffic Calming)정책의 도입, 집단 등․하교제 시행, 신호주기 확대 실시 등 어린이 보행권을 강화해야 한다. 어린이 통학버스 운행 관련 법규의 경우 스쿨버스의 안전을 고려한 개선, 유아전용차의 시설기준, 지방자치단체별 조례제정, 스쿨버스에 관한 법령제정 등을 통해 이를 강화해 나가야 한다. 운전교사에 대한 관리규정 역시 운전자 선발, 교육훈련 등 통학버스 보호규제 강화정책을 실시해야 함을 제시하고 우리나라 어린이통학버스 교통사고 감소시키는 방안에 이바지 하는 데 있다. The study attempts to propose alternatives of reducing the number of traffic accidents associated with children's commuting. The lessons from those advanced country's experiences with low accidents will help it reach the conclusion. For an effective work, the research will proceed the followings. Chapter 1 clarifies the purpose of the study and describes the research method as well. Chapter 2 discusses on literature review not only for understanding the current status of accidents but also for setting up the analyzing framework. Chapter 3 focuses more on the refining the research framework and the flow of the study for clarifying the purpose of the work and the research method. It also proposes criteria of effective comparison on the system among those selected countries. Chapter 4 compares institutions and system related to reducing and managing the children's safety of four major countries: USA, Germany, England, and Japan. Chapter 5 collects lessons from the comparison and proposes idea and alternatives for securing the children's traffic safety as conclusions. The most frequent cause of children's death was safety accident, of which traffic accident took the half. There are data from Load Traffic Authority that analyzed various causes of frequently occurring children's traffic accident. The most frequent cause was the invasion of central line, and then the violation of traffic signal, the safety distance unsecured, the violation of safe driving duty, the violation of intersection passing method and the violation of pedestrian protection duty in order. First, out of accidents happening from driver's violating traffic-related laws, there were problems related with traffic laws like the violation of safety duty, the violation of signal and the violation of central line, Second, there were problems related with the management of school zone, as most of children's school bus accidents took place at the school zone. Third, there were problems related with the management of drivers, as the main cause of children's school bus accidents were mistakes of drivers. Lastly, there were problems related with the preventive education to children's traffic accident, because children's low reaction to traffic accident resulted in lots of victims as they are mentally and physically weak and did not receive enough traffic education. As above, this study tried to research 4 kinds of problem, the causes of children's traffic accident, including the school zone management plan, the traffic-related laws and system, the management of drivers and the children's traffic accident preventive education. The results showed that reinforced laws and punishment should be introduced to school zone, and children's right to walk should be reinforced such as the introduction of traffic calming policy, the implementation of collective commute system and the implementation of expanded signal cycle. The children's school bus service-related laws should be reinforced through the improvement considering the safety of school bus, the standard of car for infants' exclusive use, the revision ordinance according to each local government and the enactment of school bus related laws. As for administrative regulations for teacher drivers, a reinforced policy of school bus protection and regulations like selection of drivers and education and training should be carried out. This thesis will contribute to reduction of domestic children's school bus accident.

과거 대화 정보와 화자를 고려한 대화 키워드 추출

고준호 경북대학교 대학원 2013 국내석사

A number of methods have been studied for keyword extraction from written text. They extract keywords basically based on word information such as term frequency or semantic meaning. Recently keyword extraction from spoken text is becoming more important. Spoken text has several characteristics unlike written text. They are speaker centric information and speaking time information. However, existing methods do not consider them. To resolve this problem, this dissertation proposes a method that consider characteristics of spoken text. For this purpose, in this dissertation uses the history of user's dialogue information which contains above three kinds of information. Word information is represented by graph structure using co-occurrence information between words. Also, speaker centric information is represented by graph structure using words mentioned by each speaker. Speaking time information uses forgetting curve(Hermann Ebbinghaus, 1885) that control relationship information between words in above graphs. The proposed method is evaluated with two kinds of data sets: the National Assembly transcript in Korean and the ICSI meeting corpus in English. Through experiments, the proposed method showed a better performance in extracting keywords than comparison models. And this dissertation show how the performance varies according to different changes of the method proposed.
